OC Go (2011-2041) Information

Measure M1 delivered $4 billion worth of transportation improvements between 1990 and 2011. Through early action and capitalizing on financial opportunities, more than $1.2 billion in additional funds were leveraged for M1 improvements. After experiencing the success and progress of M1, nearly 70% of Orange County voters renewed the half-cent sales tax for transportation improvements in November 2006 for another 30 years to launch Measure M2. In 2017, Measure M2 was rebranded as OC Go. By the year 2041, the OC Go Transportation Investment Plan program plans to deliver over $13.1 billion* worth of transportation improvements to Orange County. Major improvement plans target Orange County freeways, streets and roads, transit and environmental programs.
